Description

container switch

technical field

The present invention relates to a container, in particular to a container for discharging pastes, fats, milks and other similar products, hereinafter referred to as liquids.

Background technique

There are a wide variety of containers available for the controlled discharge of a liquid product through an outlet having a control switch in the form of a flexible membrane with a nose or stud which, due to deformation of the membrane, acts to close the outlet Moves between a position that prevents liquid from draining and an open position that allows liquid to drain through the outlet.

One such device is disclosed in U.S. Patent No. 5,454,494, wherein the membrane is mounted on a hollow cylindrical support and then placed in a rigid insert in the container, and the liquid flows from the container through a cylindrical channel. To the discharge chamber, when the liquid in the container is pressurized, it is discharged from the chamber with the deformation of the membrane.

The assembly described in US Patent No. 54544994 has many disadvantages, not only does it comprise a large number of parts, but also they are complex and difficult to assemble.

The assembly process is complicated by the fact that the rigid insert will be placed in the upper region of the container, the insert must be inserted from the bottom of the container, after which the container can be sealed. It is therefore obvious that the above-mentioned containers cannot be mass-produced.

In addition, the insert is constructed such that liquid flow from the container body to the discharge chamber is confined by a cylindrical passage having an overall cross-sectional area substantially smaller than the cross-sectional area of the container and/or discharge chamber.

Also proposed in U.S. Patent No. 5,325,999 is an assembly comprising a composite flexible membrane member forming an arched control switch that opens and closes when the arch is deformed by pressurized liquid within the container Close the corresponding outlet. However, the structure of this component is also rather complex and not suitable for mass production.

In addition, the liquid flow from the container body towards the outlet passes through a single intermediate channel, which imposes many restrictions on the flow rate, the nature of the liquid that can be discharged, and especially the viscosity; at the same time, the structure of the assembly is such that the outlet must be offset from the intermediate channel. Therefore, the position of the outlet of the module is limited, and the possibility of placing the outlet in the middle, which is often requested, is lost.

DE-A1-4329808 discloses a container or pipe in which discharged liquid is supplied to the discharge chamber through a pair of diametrically opposite flow openings. These openings comprise narrow cylindrical passages whose overall cross-sectional area is again considerably smaller than the cross-sectional area of the container and/or the discharge chamber, so that the flow of liquid to the discharge chamber is still highly restricted.

US 2695119 discloses a collapsible tube that delivers liquid to the cavity of the tube cap through a plurality of small holes in a plug axially movable within the tube, under the control of a switch member located in the movable plug, Liquid is discharged through an outlet in the cover, defining an interior chamber in the switch member which vents to the atmosphere through an angled hole formed in the plug aligned with the opening in the lower wall of the switch member, at the other end Align with the opening in the wall of the cover.

The entire assembly described above is complex, difficult to assemble, and has limited fluid flow from the tube to the cavity of the cap.

Now see US 2607515 and US 2643794, they all disclose container, but their structure all makes manufacture and assembly have many difficulties.

Contents of the invention

There is a need to be able to provide a container for discharging liquids which is of simple construction and which can be assembled automatically so that it can be mass-produced and which has improved flow characteristics compared to known devices and which can handle a wider range of liquids.

According to the present invention, there is provided a container comprising a body member for holding a liquid, and an outlet portion positioned at one end of the body portion through which the liquid flows out when the interior of the body portion is pressurized, and an outlet portion positioned at one end of the body portion. The cover on the part has at least one outlet to discharge liquid from the outlet part of the body member, and a control assembly on the cover part is used to control the discharge of liquid from the body member to each outlet of the cover part, each The control assembly of the outlet consists of a control switch and a seat for said control switch, the control switch is molded from a single piece of plastic, which includes a membrane part and a nose protruding from said film part, and the seat consists of an outer ring A sleeve forming an extension of the outlet portion of the body member in the cover portion, within which there is a support cavity for the switch having an inoperative position in which the nose of the switch engages and Corresponding outlets on the sealing cover portion, one or more holes protrude from the support cavity, the design is such that when the interior of the container is pressurized, the liquid passes from the body member along the flow path through the gap between the outer collar and the switch support cavity. Seat flows to the membrane portion of the fit switch and deforms it, so the nose of the switch is released from the outlet and the liquid is expelled through the outlet; after the pressure inside the container is released, the control switch returns to its resting position, at which point its The nose seats and seals the outlet.

It is characterized in that the one-piece plastic molded seat having a support cavity includes side walls defining an open top of the support cavity upon which the switch is seated engages the support cavity, defined in said cavity below the switch An inner space, the side walls of the support chamber are interconnected with the outer annular sleeve by a plurality of thin, circumferentially spaced ribs, thereby creating a large space between the sleeve and the support chamber for liquid to flow from the body member to each outlet , the hole protruding from the support cavity passes through the side wall, passes through one or more ribs and the annular sleeve, and makes the inner space of the support cavity open to the atmosphere.

It can be seen that with this design, each control switch and seat is a single structure and each is molded from a suitable plastic, thus reducing the number of components of the container and making assembly easy.

The switch support cavity is open to atmosphere and prevents pressure build-up in the closed space below the switch that may occur during assembly and prevents pressure build-up in conditions such as high temperatures that would affect the movement of the opening between its open and closed positions There is a negative effect, so the communication helps to increase the elasticity of the control switch, which can ensure that the control switch returns to the stop working position quickly and effectively after the pressure inside the body member is released.

In addition, the relatively large space between the housing and the switch support cavity is only affected by relatively narrow connection ribs, which provides excellent flow characteristics from each outlet of the body member to the cover, so that the container can discharge Liquids of various viscosities.

The container may include a one-way switch means which closes the interior of the container to atmosphere when the interior of the container is pressurized and which opens to atmosphere the interior of the container after the internal pressure of the body member is released.

Typically, the one-way switch means includes or has a bottom wall perpendicular to the direction of flow of liquid from the container to each opening.

In one embodiment of the invention, the control switch comprises a cylindrical skirt which sits and surrounds the upper region of the side wall of the support cavity, so that the control switch is sealingly seated on the support cavity.

In this embodiment, the skirt of the control switch may be molded on the upper region of the side wall of the support cavity.

In another embodiment of the invention, the control switch comprises a cylindrical skirt partly closed at one end by a membrane, which skirt is received in the upper region of the side wall of the switch support cavity, so that the switch is located sealingly above the cavity.

In this embodiment, the upper region of the side wall of the switch support chamber may have an annular inlet which is adapted to receive the skirt of the switch so that the switch is sealingly located in the upper region of the chamber.

The outlet portion of the body member may be defined by a cylindrical neck, and the sleeve of the seat encloses the upper neck to position the seat on the body member. As an example, the jacket can be snap-fitted over the neck, or screwed onto the neck.

The outlet portion of the body member may be defined by a cylindrical neck with which the outer collar of the seat is integrally molded, whereby the body member and seat form a single unit.

The cover portion is preferably movable relative to the body member between a closed position which prevents flow of liquid from the body member to each outlet and a discharge position which permits flow of liquid from the body member to each outlet when pressure builds up inside the body member.

Movement of the cover part between the closed position and the discharge position may be accomplished by axial movement of the cover part on the body member, or by rotation of the cover part relative to the body member.

Alternatively, the lid portion may be molded integrally with the seat and is hingedly movable relative to the seat between an operative position in which the container is closed and each control switch housed therein, and in the inoperative position for the control switches And the seat provides the entrance.

A container according to the invention includes a cover member mounted on the outside of the cover portion, the cover member providing a plug portion for each outlet, the cover member being movable between a closed position and an open position in which each Each plug seats and seals a corresponding outlet, and in the open position, each plug is partially removed from the corresponding outlet.

The lid member is preferably integrally molded with the lid portion and is rotatable about a hinge of reduced thickness relative to the lid portion between its open and closed positions.

In a further embodiment of the present invention, the container includes a plurality of outlets, and each outlet is equipped with a control switch and a corresponding seat in the container, and the seats are integrally formed with each other, and the outside of the container also includes a plurality of brushes, the brushes A brush protrudes from the area near the outlet to receive the product discharged from the container for brushing.

Alternatively, the brushes may be replaced by a sponge or similar applicator on the outside of the container, which may be used, for example, for shoe maintenance or polishing.

In a preferred embodiment of the invention, the body member of the container is made of flexible plastic so that its interior can be pressurized by squeezing the body member and the liquid subsequently discharged.

The control switch is usually made of a thermoplastic material such as rubber or silicone rubber, thereby ensuring a leak-proof and drip-free seal between the nose and the corresponding outlet, as well as a leak-proof seal of the switch skirt in the support cavity.

Detailed ways

Reference is now made to Figures 1 and 1a which show the components of the container comprising a flexible plastic body part or reservoir 2 including a neck 4 with an external thread.

The switch seat of high density polyethylene is usually indicated by 6, which includes an outer ring 8, forming an inner cavity suitable for seating and screwing on the neck 4 of the container at its lower part, thereby fixing the seat 6 to the body part 2 Above, the inner wall of the sleeve 8 is located in the neck 4 and defines an outlet of the body part 2 .

Molded integrally with the sleeve 8 is a cylindrical switch support cavity 12 connected thereto by a plurality of thin, circumferentially spaced ribs 10, initially open at its upper and lower ends. The upper part of the chamber 12 has formed therein an annular inlet 14, the purpose of which will become clear below.

An elastomeric or silicone rubber control switch of soft thermoplastic material is generally indicated at 16 and includes an annular skirt 18 closed at its upper end by a circular membrane portion 20 on which an intermediate nose is formed. Section 22.

The skirt 18 of the control switch 16 is hermetically friction fit over the inlet 14 of the chamber 12 whereby the switch 16 is sealingly located in the upper portion of the chamber 12 . Additionally, to ensure sealing engagement of the cavity 12, a skirt 18 of the switch may be molded over the cavity 12.

The volume of cavity 12 below switch 16 is vented to atmosphere, and one or more holes 24 formed in seat 6 project from the lower portion of cavity 12 through sleeve 8 along and through one or more ribs 10, whereby the cavity 12 The volume in the lower part is connected to the atmosphere by the above-mentioned holes.

A gas plug or one-way switch 23 is received in a bore at the lower end of cavity 12 . This switch 23 will be described in more detail below, and it has a first position, is seated in the lower end of cavity 12 in this position, to define the closed volume that opens to atmosphere through hole 24; This location communicates with the chamber 12 inside the container.

When the switch 16 is in the cavity 12, the upper portion of the defining wall of the cavity 12 protrudes upwardly beyond the upper surface of the membrane portion 20 of the switch 16, forming a groove 25 in the upper portion of said wall, the purpose of which will be apparent below.

The container is completed by a cover 26, such as high density polyethylene, having a central outlet 28, which is pressed onto the sleeve 8 of the seat 6 and is rotatable relative to it.

The upper surface of the cover 26 comprises an annular projection engaging the upper free end of the wall of the chamber 12, an inner shroud sealing over the groove 25 when the cover 26 is in its closed position, thereby defining together with said projection a switch 16. Just above the closed space inside the cover. In the closed position of the cover 26 , the nose 22 of the switch 16 seats and seals the outlet 28 .

To discharge the product in the container, the lid 26 is turned to move the cover plate away from the slot 25 and the body of the container is pressurized to increase the pressure inside the container. This increased pressure forces the product in the container through the annular space limited only by the narrow ribs 10 between the sleeve 8 and the outer wall of the cavity 12, through the groove 25 in the wall of the cavity 12, into the diaphragm portion 20 of the switch 16 The upper surface fits.

The membrane portion 20 then moves downwards into the chamber 12, whereby the nose 22 moves away from the outlet 28 through which the product in the container is expelled.

At the same time, the increased pressure in the container forces the one-way switch 23 into a position that seals the hole on the lower end of the chamber 12, preventing the liquid in the container from entering the chamber 12 and preventing the airflow from the chamber 12 from entering the container.

When the pressure on the body portion is released, the switch 16 returns to its normal resting position, with its nose seated and The outlet 28 is sealed, thereby terminating the discharge of the container product.

Simultaneously, the one-way switch 23 moves to its second open position due to the differential pressure, allowing atmosphere to flow from the chamber 12 through the lower portion of the chamber 12 into the container, thus helping the container to return to its normal inoperative condition.

While the one-way switch is not required, it is very useful for the container to return to its natural shape, which can be very slow otherwise.

Although the chamber 12 is shown communicated with a one-way switch 23, it could also be a hole 24 or communicate only with the atmosphere, in which case the lower end of the chamber 12 would be closed by a transverse wall 13.

The sealed space in the cavity 12 below the switch 16 is vented to the atmosphere, and the switch 16, which moves with the ribs, returns to its normal resting state when the pressure in the body part 2 is released, preventing a leak in this space during assembly. Pressure builds up and prevents pressure buildup due to, for example, high room temperature, which would negatively affect the movement of switch 16 between its open and closed positions.

It can be seen that the structure of the above-mentioned container is simple and cheap, especially when the seat 6 and the switch 16 are each integrally molded, a single part can be easily placed on the body part 2, and in fact it can be achieved by combining the seat 6 with the switch 16. The body part 2 is integrally molded to further reduce the number of parts. Therefore this design is especially suitable for automatic assembly.

In addition, by providing a large space between the sleeve 8 and the chamber 12 as a liquid passage, in which there are only very narrow interconnecting ribs 10, regardless of the viscosity, the Flow of fluid product from body portion 2 to outlet 28 .

The switch 16 acts at the exact point of product discharge and clears invisible and unsanitary accumulation of used product on the outlet of the container, which ensures reliable drip-free operation. The container of the present invention is designed to have a more attractive and hygienic appearance than existing containers, resulting in a very mobile and broad interest and market use.

Since a cream, fat, milk or similar product is discharged through the top of the container, it is possible to apply the product directly to the hands or legs, and to carry out the cleaning work by simply wiping the cover against the skin surface.

The semi-seal effect of the control switch 16 on the outlet 28 means that the container can be lifted to the open position of the lid 26, either up or down, for immediate use without the usual risk of leakage.

The closed position of the cover 26 provides leakage insurance against accidental squeezing during travel or other occasions.

The precise means by which the cover 26 moves from the closed position to the open position can vary, in a rotational arrangement as shown in Figure 1, there could be a series of slots cut around the top of the cavity 12 with a corresponding series of shrouds in the cover.

Figures 2a-2c show a design similar to that of Figure 1, in which corresponding parts have been given the same reference numerals. A cover plate 30 within the lid 26 cooperates with the cavity 12 and overlies the slot 25 when the lid 26 is in the closed position shown in Figure 2c.

Figure 2a shows that the cover is turned from its closed position, such as 90°, to its open position, and Figure 2b shows that when the body part 2 of the switch 16 is pressed and then the nose 22 moves downward as clearly seen in Figure 2b, the liquid Exiting from outlet 28.

Movement of the lid 26 from its closed position to its open position is accomplished by axial movement of the lid relative to the body portion 2 of the container, as shown in Figures 3a-3c.

In particular, this embodiment does not include the groove 25 in the upper part of the cavity 12, which has a continuous rounded upper edge. The lid 26 includes on its inner surface an annular protrusion 32 which, when the lid 26 is in its closed position, engages on the upper free edge of the chamber 12, forming a closed space above the switch 16 and sealing the outlet 28 inside the container. .

In addition, in the closed position of the cover 26, the switch 16 is elastically moved by the cover 26 from the normal resting position to the pressed position on the seat 6 as shown in FIG. 3a.

When the cover 26 axially moves upwards to the position shown in Figure 3b, the protrusion 32 on the cover 26 leaves the cavity 12, and the released switch 16 returns to its normal stop working state, and its nose 22 seats at this time. Dropping and sealing the outlet 28, the product in the container 2 contacts the switch 16 in the lid 26.

The discharge of the product in the container 2 is produced by pressurizing the body portion 2 of the container as indicated by arrow "A" in Fig. 3, whereby the pressure inside the container is increased due to the pressurization, thereby expelling the liquid as described above.

It should be appreciated that the position of the lid shown in Figure 3a provides a useful shield for the container, as an example, to ensure that it does not vent or leak during travel.

The embodiment of FIGS. 3 a - 3c does not include a gas plug or one-way switch 23 , and the lower end of the cavity 12 is closed by the transverse wall 13 . This embodiment is especially useful for containers containing high viscosity products with sandwiched tubes.

Figure 4 shows a modified seat compared to Figures 1 and 1a. In particular, cavity 12 is offset from the center of sleeve 8 and supports a switch 16 therein which controls flow through a correspondingly offset outlet 28 of cover 26 . The interconnecting ribs 10 move accordingly so that the space between the sleeve 8 and the cavity 12 for fluid flow is crescent shaped rather than circular. However, compared with the prior art, the overall mode of operation and advantages of this embodiment are the same or similar to those of the embodiment of FIG. 1 . Obviously, the precise relative position of cover 8 and cavity 12 can be changed as required, seat 6 as a whole, its basic shape also can be such as ellipse instead of circle, and the opening of cover 26 can be controlled by cover as shown in the figure 3a-3c in the embodiment by axial movement. In addition, a vent hole 24 is shown extending from the lower portion of the chamber 12 to the atmosphere through a rib 10 .

Figures 5 and 6 show an embodiment similar to that of Figure 1, however it is provided with a cover member 32 integrally molded with the cover 26 and connected to the cover 26 by living hinges 34 of reduced thickness, the cover Member 32 includes a centrally attached plug 36 that seats and closes outlet 28 when it is in the closed position of FIG. deformation. This closed position of the lid member 32 prevents accidental discharge of liquid from the container during travel or the like.

In an alternate embodiment, the plug 36 may be replaced by a cap that sits over the outlet 28 rather than protruding into the outlet 28 .

The lid member can be pivoted about hinge 34 to an open position as shown in Figure 5, at which point liquid can be drained as desired. The ventilation holes between the lower space of chamber 12 and the atmosphere are clearly shown in FIGS. 5 and 6 .

In a non-illustrated embodiment of the invention, the lid 26 is integrally molded with the seat 6 and connected by a living hinge of reduced thickness, thus further reducing the number of container components.

Alternatively, the seat 6 may be integrally molded with the body portion 2, and the body portion 2, seat 6, cover 26 and cover member 32 may be formed as one piece.

Figures 7a and 7b show a modified container of the invention for applying the product contained in the container in a brush-like manner.

In particular, the squeezable body part 2 comprises three separate switches 16, each supported on its respective seat 6, the three seats forming a single support 38 integrally with each other. The three switches 16 themselves can be interconnected for ease of assembly.

A cover 26 snaps onto the body part 2 and includes three outlets, each receiving a nose 22 of a corresponding switch 16, sealing said outlet 28 in the same manner as in the previous embodiment.

The outside of the cover 26 between the outlets 28 is equipped with a group of brushes 40. It can be seen that when the body part 2 is squeezed, the product in the container is discharged to the brushes 40 through the outlets 28, thereby performing the following as required. Operation, the switches 16 work in unison with each other.

The nose 22 of the switch 16 can extend just past and beyond the corresponding outlet 28, thereby facilitating application of the product discharged from the container to the brush 40, while the brush 40 can be replaced with a sponge, cotton or other applicator for use with For example, the maintenance and polishing of shoes.

In the embodiment described in detail above, the control switch 16 is located in the cavity 12 of the seat 6 as a separate component. However, as previously mentioned, the control switch could be integrally molded with the seat, for example molded onto the top of cavity 12, thus further reducing the number of container components.

In one embodiment, the control switch 6 may not include the skirt 18, and the outer edge of the lower surface of the membrane portion 20 away from the nose 22 may also be molded into the upper region of the cavity 12 so that the cavity below the membrane portion 20 12. Determine an enclosed space.

Obviously, the precise configuration of the container may vary from the examples described and illustrated above, all without departing from the spirit of the invention. For example, the nose 22 or each switch 16 could be a narrow strip and receive a corresponding narrow outlet therein, whereby the spraying action is obtained as the internal pressure of the container increases. Additionally, the nose 22 or each switch may not be round, they may have concave outer ends as an example.

FIG. 8 shows an alternative control switch 42 whose nose includes a hollow cylindrical stem 44 topped by a soft rubber plug portion 46 . The membrane portion 48 is stepped and terminates in an attached skirt 50 . Other modifications and variations will be apparent to those skilled in the art.

Although the pressurization of the product in the container by deforming the container itself has been described, this pressurization could also be done using eg a pump type device inside the container.

Accordingly, the container described above is relatively simple in structure, can be produced economically and can be assembled automatically, which provides the customer with various advantages over existing products.

In particular, the container of the present invention enables the customer to smoothly discharge liquids of various viscosities in large or small drops.

The size of the outlet and switch can be easily changed to adapt to different products and customer discharge requirements, and it can be adapted to a wide range of products from high-viscosity lipids to water.

The container can be upright, semi-rigid, or inverted. In all cases, regardless of direction, the outlet can be sealed by a resilient control switch.

The venting of the switch support chamber to atmosphere enables the container to return quickly to its normal condition and ensures that the control switch is moved quickly and efficiently to and from the inactive and removed positions. In addition, the ventilation system can still work even if the outlet 28 is closed.

Since the lower end of the cavity 12 is initially open, the control switch can be easily molded to the upper end of the cavity 12, and a corresponding mold can be inserted through the cavity from the bottom up for proper molding. The one-way switch 23 can be inserted into the working position at the bottom of the cavity 12 .
